    1. If you reflect a graph in the x-axis then you are simply taking whatever answer you get for y, and turning it to -y.
    So y(x)=x becomes
    -y(x)=x => y(x) = -(x)

    2. Reflecting a graph in the y-axis swaps around the values of x with the values of -x. So y(-x) = x => y(x) = (-x)

    In this case both of the answers are the same.
